Can someone tell me where the factory amp is grounded in this picture? (PIC)

[JuBu]

Where is it grounded? Or is there a ground wire going somewhere else located in that big bundle of wires?

Ok, I've just been told that the ground wire is actually located within that bundle of wires. Anyone know which one?

Hope this helps. Pin Out from a 96' factory amp.

Pin #1- Left front speaker output (+)---- color: yellow/red Pin#2- Right front speaker output (+)----color: blue/red Pin#3- Left rear speaker output (+)----color: yellow/black Pin#4- "Mute" for the telephone color: white/brown Pin#5- Power (Hot in ACC and RUN) from fuse # 44----color: violet/white Pin#6- Right rear speaker output (+)----color: blue/black Pin#7- CD Changer (I-Bus)----color: yellow Pin#8- Left front speaker output (-)----color: brown/orange Pin#9- Radio Memory Power (stations etc.) (HOT at all times)(from fuse #9)----color: red/white
Pin#10- Variable road noise volume adjustment input (from the tach)----color: black/white (with HK system, this is only on with Hi-Fi switch on) Pin#11- Right front speaker output (-)----color: brown/orange Pin#12- Left rear speaker output (-)----color: brown/orange Pin#13- Radio lights (from dimmer and headlight switch)----color: gray/red Pin#14- Right rear speaker output (-)----color: brown/orange Pin#15- Ground
Pin#16- Antenna amplifier output----color: white

So brown/orange Pin#15- Ground would be your answer. I would check it with a meter to be safe.
